more atlas than textbook, which is good. it looks best for curious wandering and side by side checking, not for settling every taxonomy argument when different backbones disagree.

Great design, very snappy. Fun to browse and learn about species I didn't know exist and see how species are related to each other.

Super cool! I just learned about 'incertae sedis' from here—though I think these things should at least be in their kingdom (e.g. Naldaviricetes are clearly viruses no?)

Some of the mouse-overs don't seem to match, hovering over 'viruses' shows a raccoon, and hovering over 'lungfish' shows a bird eating a fish

Very cool. Perhaps you've seen OneZoom[0] already which is purely based on phylogenetic data sourced from Open Tree of Life. OTOL has been around for a long time. The project aggregates phylogenetic data from thousands of studies and creates a massive synthetic tree.[1] It's neat because anyone can contribute. If you find a study not represented in there you can contribute the newick tree/annotation for it. [0] https://www.onezoom.org/ [1] https://tree.opentreeoflife.org/opentree/argus/ottol@378964/...
